From Kitchen to Table: A Safe Software Journey with SBOMs

SPEAKER: Dmitry Chuyko   COMPANY: Bellsoft

KEYWORDS: Cloud, Security, Technology, Tools

Think of your containerized Java application as a complex dish served to production. Your software supply chain is a kitchen. Would you trust a kitchen with hidden ingredients? SBOMs are the ingredient manifests that health inspectors (scanners) and regulators (compliance) demand.

JDK Doping: Performance Gains Without Touching Your Code

SPEAKER: Dmitry Chuyko   COMPANY: Bellsoft

KEYWORDS: Language, Open Source, Performance, Technology

One reasonable desire is to speed up existing deployments without affecting code and diagnostic tools. Too many resources are spent on profiling, optimizing, and updating applications. At the same time, we need to improve hardware utilization, and frameworks and runtimes are reaching the end of their lifespan.

Kill your Tests

Wie wir den E2E-Sumpf mit KI-Agenten endlich trockenlegen

SPEAKER: Felix Tensing   COMPANY: NÜRNBERGER Versicherungsgruppe

KEYWORDS: AI, Lessons learned, Testing, Tools

Wir kennen es: Die E2E-Testsuite wächst schneller als der eigentliche Feature-Code. Was als gute Absicht begann, endet in einer unübersichtlichen Sammlung von Copy-Paste-Wüsten, die ewig laufen und am Ende doch nur Zufallsergebnisse in einer chronisch roten Pipeline liefern.

Raft von Hand: Was zwischen dem Paper und einem produktiven Cluster liegt

Vom Konsensalgorithmus zum verlässlichen System in Produktion

SPEAKER: Felix Berger   COMPANY: fbt Berger – Future Build Technology Berger

KEYWORDS: Architecture, Open Source, Tools

Wer Kubernetes, Kafka oder Consul betreibt, verlässt sich täglich auf einen Konsensalgorithmus - meist ohne je einen gesehen zu haben. Er ist der Grund, weshalb sich ein Cluster auch dann noch auf eine gemeinsame Wahrheit einigen kann, wenn einzelne Knoten ausfallen oder das Netzwerk auseinanderbricht. Und er ist der Grund, weshalb nicht zwei Knoten gleichzeitig glauben dürfen, sie hätten das Sagen.

Raft gilt als einer der verständlicheren Konsensalgorithmen. Leader Election und Log Replication lassen sich im Paper auf wenigen Seiten erklären. Doch zwischen einem verständlichen Algorithmus und einem Cluster, dem man Produktivdaten anvertraut, liegen einige überraschend schwierige Details.

Beyond Hype

An Engineering Approach to Evaluating Coding Assistants

SPEAKER: Robert Munteanu   COMPANY: Adobe

KEYWORDS: AI, Tools

AI coding assistants are quickly becoming part of everyday development workflows, and teams are starting to invest in agent-specific tooling such as reusable skills, repository instructions, and external tool integrations. But before adopting or expanding that tooling, we should ask a basic engineering question: does it actually improve results? A higher task success rate is useful, but it is not enough on its own. Speed, cost, and reliability matter too.

The Architecture of Power: Structural Change Without Authority for Software Engineers

SPEAKER: Yevgen Nebesov   COMPANY: Self-employed sociotechnical engineer

KEYWORDS: Lessons learned, Teamwork

By the time an external consultant arrives to redesign your development organization with the latest methods and frameworks, a decisive battle has already been won: someone has secured the mandate to change it.

But what if you are the software engineer who sees what could work better, yet cannot redraw teams, redirect budgets, or tell others how to work?

Raft by Hand: What Lies Between the Paper and a Production Cluster

From Consensus Algorithm to a Reliable System in Production

SPEAKER: Felix Berger   COMPANY: fbt Berger – Future Build Technology Berger

KEYWORDS: Architecture, Open Source, Tools

Anyone running Kubernetes, Kafka or Consul depends on a consensus algorithm every single day – most likely without ever having seen one. It is the reason a cluster can still agree on one shared truth when individual nodes fail or the network splits apart. And it is the reason two nodes must never both believe they are in charge.

Raft is considered one of the more approachable consensus algorithms. Leader election and log replication fit into a few pages of the paper. Between an understandable algorithm and a cluster you would trust with production data, however, lie a number of surprisingly hard details.
